Startup script jython.bat brought by Windows installer breaks in case %
CLASSPATH% variable has spaces in it (even if the path components 
containing spaces were surrounded by double quotes).

just to be sure: you are not talking about the current beta (2.5b...)

I'm talking about this one:

C:\apps\jython_2.2>jython.bat --version
Jython 2.2 on java
msg5419 (view) Author: Jason R. Coombs (jaraco) Date: 2010-01-08.23:14:41
This problem still exists with Jython 2.5.1.

To reproduce, install jython, then install Quicktime (or iTunes), then try to launch jython. Output is:

\QuickTime\QTSystem\ was unexpected at this time.

This is apparently due to QuickTime adding its java lib to the global classpath:

CLASSPATH=.;C:\Program Files (x86)\QuickTime\QTSystem\

Who would have thought that buying an iPhone required breaking Jython in Windows?

I'm not sure it's possible to create a batch file that properly handles paths with spaces and quotes in them. I've seen the Apache Tomcat project struggle with this since time=0.

Perhaps a jython.exe bootstrapping executable would do the trick.

Please report back here if there is any proposed solution to this problem. I'm happy to contribute to help get this resolved.

TimVukman reported the same under Windows7, using jython 2.5.1

Spaces and quotes are not the problem here - the round brackets around x86 in the path come in the way.

The following CLASSPATH works:

CLASSPATH=.;C:\Program Files\Java\jre6\lib\ext\

c:\Users\bagside\stuff\jython\jython-2.5.1>if not defined _BOOT_CP (if defined CLASSPATH (set CLASSPATH=c:\Users\bagside\stuff\jython\jython-2.5.1\jython.jar;.;C:\Program Files\Java\jre6\lib\ext\ )  else (set CLASSPATH=c:\Users\bagside\stuff\jython\jython-2.5.1\jython.jar ) )

while a CLASSPATH containing (x86) screws up the batch file:

CLASSPATH=.;C\Program Files (x86)\Java\jre6\lib\ext\

c:\Users\bagside\stuff\jython\jython-2.5.1>if not defined _ARGS goto argsDone
\Java\jre6\lib\ext\ was unexpected at this time.

c:\Users\bagside\stuff\jython\jython-2.5.1>    set CLASSPATH=c:\Users\bagside\stuff\jython\jython2.5.1\jython.jar;.;C\Program Files (x86)\Java\jre6\lib\ext\

A possible solution could be to replace

if not defined _BOOT_CP (
  if defined CLASSPATH (
    set CLASSPATH=%_CP:"=%;%CLASSPATH:"=%
  ) else (
    set CLASSPATH=%_CP:"=%


rem do not use 'if () else ()' because this does not work with CLASSPATH containing (x86)
if defined _BOOT_CP goto fullCmd
if defined CLASSPATH goto classpathDefined
set CLASSPATH=%_CP:"=%
goto fullCmd

Good point. I assumed it was the spaces issue, as that's usually the offending character, and since there was an open bug, it seemed appropriate. Thanks Oti for catching that.

I've created issue1548 to capture the parenthesis issue separately.

Coming back to the original message (

Downloaded jython 2.2.1 from,
installed it,
tested id with a CLASSPATH containing a blank space,
and it worked - see output below:
